I'm working on building a special object, a pillar with a mirrorlike square atop it. This will be placed in a dark room where probably the only light will be from a player. Right now I'm toying with trying to get the mirror material as glossy as possible without it emitting any light, because it'll look silly if it glows in a dark area. I'm not sure if it's entirely possible anyways to do this.
Here's what I have so far. It looks okay outside, except for the UV being mostly upside down.
However, when indoors, it gets a speckled pattern and glows on the dots.
Some looking into the matter shows that most shiny objects in the game actually do emit light, as this diamond shows in total darkness.
So I've got two major things to solve. First off, the speckles need to be made into more of a gradient of light, like most objects such as windows or other flat glossy planes reflect in. I don't know what property controls the pattern it glows in aside from the glowmap, which I've tried setting to solid black or removing completely.
The next problem is getting it to be reflective without emitting light. I may end up toning down the gloss if it hides the emission of light, or turning it off completely and making a texture that looks the part instead. I'll be glad to hear it if anyone knows how to do either.
For reference, I am using the texture from the ingame diamond that's got a flat normal map with a solid black alpha channel, and no glow map.
